Chargers defensive end Joey Bosa found his way atop of Pro Football Focus’ list as the No. 1 overall player on their top-25 NFL players under the age of 25.

Bosa finished the 2017 season with 12.5 sacks, 70 tackles (54 solo), four forced fumbles, one fumble recovery and one pass defensed. On Oct. 29, he surpassed former 49ers defensive end Aldon Smith’s NFL record for most sacks through a player’s first 20 games in NFL history with 18.5 by sacking Patriots quarterback Tom Brady. Bosa had his jersey and game-worn gloves put on display in the Pro Football Hall of Fame.

This success helped the former Buckeye earn his first Pro Bowl selection. Bosa’s high level of production also saw him and outside linebacker Melvin Ingram the first Chargers duo to record double-digit sacks in the same season since 2006 when both Shawn Merriman and Shaun Phillips accomplished the feat.

As a rookie in 2016, Bosa earned the highest-ever grade for a first-year edge defender at 89.8. His 59 total pressures that year (37 hurries, 11 QB hits, 11 sacks) were the most we have ever seen through a player’s first 12 games, but he wasn’t done there. Bosa took his play to another level in 2017, solidifying himself as not only an elite player for his age, but among the entire NFL. Bosa’s 2017 pass-rush grade of 93.2 led all edge defenders while his 46 combined hits and sacks since entering the league in 2016 ranks sixth. At only 22 years old, Bosa could hold the top spot down for years to come.
